IMPROVEMENT IN PAPER ENVELOPES.

Specilicaton forming part of Letters Patent No. 45,30 l, dated November 29, 1864.

To all whom it may concern:

Be it known that I, RICHARD SIIEPARD, of Brooklyn, in the county of Kings, in the State of New York, have invented a new and useful Ilmlrovement in Paper Gases or Envelopes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure I is a perspective view of the en velope or paper case when completed. Fig. II is aview oi the envelope before being folded.

To ena-ble Ihoseskilled in the art to make my envelope, I will proceed to describe its cmst-ruction. i

The paper or other material of which the envelope is formed is cut in the form shown by F ig. II. The pasteboard or stifening, indicated by thc dotted lines, and lettered A A A, .forms the bottom and ends of the envelope when completed, as shown in Fig. I, which braces and strengthens it and increases its capacit-y and convenience.

Envelopes or paper cases constructed by other methods collapse, and the material becomes broken and worn by the pressure t0 gether ot' the sides. M v'envelope, as constructed, is so braced and strengthened that the sides are held apartfaud the mouth open at all limes for the admission of papers, even alter much usage, which. is. not the case with' those in ordinary use.

The strip of pasteboard D, as shown in the drawings, materially aidsiu aecomplishingthe desired object, answering the same purpose when theenvelope is closed as the strip A does in the bottom.

I do not wish, however., to confine myself to the use of pasteboard in the construction of the pieces A A A and B, but may use any other suitable material for the purpose, except pieces of wood, t'or the ends.

ln forming the envelope, the strips A A A and B are fastened to the paper by glue or other suitable means. The flaps G G, Fig.

II, are then bent at right angles over the edges of the strips A A, forming the ends of the envelope. The llap D is bent at right angles over the edges ofthe strip A, forming the bottom of the envelope. The small flaps E E are securely fastened between the ends of the strip A and the paper which forms the bottom ot' the envelope, andthe tlap D is then folded up and secured over the tlaps C C, and forms one side ofthe paper case.

G, Fig. I, is a metallic hook secured to the side of the envelope, and H is au elastic loop attached to the lid or cover thereof. The envelope is closed by passing the loop H over the hook G, which secures it.

I am aware that a patent has been granted to John W. Wilcox on an im proved paper case or envelope', but I claim that my envelope as constructed contains many new and important advantages over his or any now in use. In my envelope the capacity' is increased, and the bottom ends and cover thereof are strengthcned by having strips of pasteboard or other suitable material placed on the inside ot' the bottom, ends, and cover of the envelope, thus bracing and strengthening all parts of it; whereas in VVilcoxs'envelope the ends only are braced by having strips ot' wood (which does not possess asmuch elasticity as my method) fastened to them, leaving the bottom and cover more liable to break than it' there u ere no braces iu the ends.

What I claim as new, and desire to secure by Letters Patent, is-

'Ihe strips A A A andB, substantially as v and for the purpose set forth.
